After watching the anime "Sonic X" and gained nostalgia feelings (last time I watched Sonic X was when it went in Sweden for many years ago), I decided to write a Sonic fanfic based on "Sonic X". So I'll choose when I want to work on this story or my Transformers stories.

A few new OCs of mine are appearing in the story. You can find the link on my Profile to see their appearances and information when I upload the rest of them. If you don't like Sonic stories with OCs, don't read then!

I'm going to follow the Japanese version, but use some dialogues from the English version here and there. Personally, I like the English version better because of the background sounds and it also has more random humor in the dialogue which I like.

Whenever Sonic or someone else speaks in Engrish, it will look like "this". And I will add some Japanese words.

Disclaimer: I do not own any Sonic X characters! I only own my OCs!

Chapter 1: The Encounter

White… That was all she could see; white and nothingness. She didn't know where she was or how she appeared in this white and empty space, but wherever she was, she felt a warm aura surrounding her while she walked or floated deeper into nothingness. Strangely, she couldn't remember who she was.

A strong light suddenly appeared in front of her and forced her to protect her eyes. She could hear a woman's gentle voice from the bright light.

"My little one… I need you to gather my emeralds."

Her eyes widened when she heard the light's request. "Who…are you?"

The light didn't answer her question, "I will teleport you to the world where my emeralds were sent to by latest Chaos Control. Please find and protect them, my little one…" The light began to shine brighter.

"Wait…!"

"I will create a partner, who will support you but you must take good care of her or you might perish…"

"P-Perish?!"

"I wish you best of luck… Mikoto the Hedgecat…"

That was the last words before the light unleashed its strength and surrounded everything with its intense power.

Mikoto was unconscious when she felt something poke her face. Groaning, she opened her eyelids and saw a small white creature in front of her. It looked a Hero Chao, but its head was formed as a Neutral Chao's, had a white diamond floating above the tip instead for a blue halo, and didn't have a yellow oval in the belly's center.

The Hero Chao exclaimed in happiness when it saw Mikoto awake. "Chao, chao!" It flew around her head with a happy smile.

Mikoto stood up slowly and rubbed her head. "Ugh… What happened? Whose voice was it in my dream?" She surveyed her surrounding while the Hero Chao decided to sit on her head. They were in a park with a fountain in the middle with a few benches around it. Mikoto walked over to the fountain and looked at her reflection.

She looked like a purple anthropomorphic female hedgehog with emerald green eyes and had peach skin. She had long quills tied up into a ponytail with a magenta braid. She wore a magenta tank top with a pink heart decoration on the chest, rose-lavender mini-skirt with black shorts, dark grey and light grey boots with white stripes, and white gloves with magenta ring bracelets. Mikoto also had a black belt with seven diamonds in different colors on it.

*I look like a hedgehog, but…the voice called me Mikoto the Hedgecat…*, Mikoto thought and looked over her shoulder. She had a long lilac tail on her back that was wagging when she tried to move it.

"Chao, chao!" the Hero Chao jumped up from Mikoto's head and flew in front of her.

Mikoto looked at the Hero Chao with slightly confused eyes, *Is this my partner the voice told me about? Probably, because I feel a connection to it…* She held out her hand to the little white creature. "Hi there…"

Mikoto chuckled lightly at the Hero Chao's actions, "You're cute. Do you have a name?" The Hero Chao stopped flying around and shook sadly its head. "I guess I have to give you a name then. How about…Diamond the Chao?"

"Chao, chao!" the Hero Chao nodded happily and hugged Mikoto's face.

Mikoto smiled lightly and rubbed gently Diamond's back. "But I will call you Dia for short. Is that okay?" Dia let go of her face and nodded.

Mikoto's ears moved when she heard voices approach them. She grabbed quickly Dia and dived into the bushes. A young couple walked past the fountain, but Mikoto noticed something about them. They were taller and didn't look like animals like she did.

*Are we…in a different world?* Mikoto thought. *The voice said her emeralds were sent to another world, so I guess they are a different species…*

When the young couple was out of sight, Mikoto and Dia went out from the bushes. "We have to find these emeralds, but how?" Mikoto mumbled.

"Chao…", Dia whimpered sadly.

*And most importantly; who am I? And why can't I remember my past?* Mikoto thought. *I hope I can find my answers while I'm searching for the emeralds…*

Mikoto and Dia went through the park and hid whenever they saw or heard a human approach them. When they were out of the park, Mikoto stared up at the tall buildings of the city while Dia looked at the vehicles. They knew if someone saw them walking on the sidewalk it would cause panic, so they went quickly to an alleyway.

Mikoto glanced up at the sky, "I think I can jump up to the roof if I bounce from wall to wall." She glanced at Dia. "You can fly after me, okay?"

"Chao", Dia nodded.

Mikoto took a deep breath and jumped on the first wall before she bounced over to the wall behind her and kept jumping until she reached one of the buildings' roofs. Dia flew after her and was happy that Mikoto was successful.

Suddenly they heard screaming and explosions echoing from the streets. Mikoto and Dia glanced down and saw a strange robot walking on the streets. It ignored the cars and stepped on them as it kept walking ahead.

"What…is that thing?" Mikoto mumbled.

"Chao…", Dia whimpered worriedly.

Mikoto saw several black/white vehicles block the way and humans carrying weapons. One of the policemen shouted a warning through a megaphone to the robot, but it didn't help. Not even the shoots the other policeman shot at the robot. The bullets just bounced off the robot and made no damage at all.

"Chao, chao!" Dia suddenly exclaimed. Mikoto looked at her and saw her Hero Chao friend point up at the sky. Mikoto glanced up and saw an egg-shaped human sit on a strange floating hovercraft. She heard him laughing evilly when they weapons didn't do any damages at the robot. The policemen tried to stop the robot with fire, but it didn't help either.

The egg-shaped man said something before the robot lifted up one of its arms and pointed its missile-shaped weapon towards the poor policemen. Mikoto and Dia closed their eyes while they heard the policemen scream in panic and fear when the robot attacked them. When the girls opened their eyes again, they saw the robot and the egg-shaped man going deeper into the city.

"We have to stop that eggman and his robot before they seriously hurt someone or destroy the city, Dia!" Mikoto exclaimed.

"Chao, chao!" Dia nodded in agreement. Mikoto and Dia followed the madman while Mikoto jumped skillfully from roof to roof with Dia following her.

Pretty soon, Mikoto and Dia saw the robot enter a skyscraper and heard Eggman command the robot, E-23 Missile Wrist, to get on the rooftop. Mikoto and Dia were only a few roofs from the skyscraper.

Eggman flew up with his hovercraft and waited for Missile Wrist when he saw several police cars reaching the skyscraper. He laughed evilly again, making Mikoto shiver.

"He's a madman…", she muttered.

"Chao…", Dia growled lightly.

While Missile Wrist was going up to the roof, it caused a few explosions in the building before it went through the roof and landed unharmed. Suddenly, a huge holographic screen appeared out of nowhere with Eggman's face in the middle of the city.

"Everyone, listen well to this! My name is Dr. Eggman. The true form of genius."

Mikoto blinked a few times, "So his name was Eggman…"

"Chao…"

Eggman continued his speaking, "Right now, I hope you all notice me via my Eggman Network. As of now, this entire world belongs to Dr. Eggman." He laughed once again.

"Is that robot yours?!" a new policeman shouted through a megaphone to the madman.

"That's correct", Eggman answered.

"Then hurry up and get your robot out of the way!" the policeman ordered him. "It could hit a plane!"

Eggman looked grumpy for a moment before he replied, "Then hand over this city to me!"

"What? What do you mean by that?" the policeman asked.

"This is what I mean", Eggman said before he snapped his fingers. Missile Wrist shot one of its missile wrists towards the ground and hit one of the police cars.

"Hand over the city!" Eggman demanded.

The policemen gave up and had to fetch the mayor. Mikoto took the chance and jumped over to the next roof while no one saw her or Dia. The lilac hedgecat glanced down at the people who looked scared and confused by the chaos.

Soon the mayor arrived and gave Eggman his answer. "We will not be ordered around by you!"

"Wrong!" Eggman chuckled evilly and snapped his fingers again. Missile Wrist shot once again its missile wrist, but now it hit a building nearby the mayor and the policemen.

"How's that?" Eggman grinned. "Have I changed your mind?"

The mayor and the policemen were covered by the dust from the last attack. "That's the decision of the leader, no, our president", the mayor coughed.

Eggman looked even grumpier that he still had to talk to one more person to conquer Station Square. "E-23, be thorough-!"

"Stop it, Dr. Eggman!" a child's voice shouted.

Everyone looked up and saw a blue plane fly towards Eggman's hovercraft. The pilot was a yellow fox and the passenger was a human child in probably 12 years.

*So I'm not the only one who came to this world…*, Mikoto thought. The plane missed slightly Eggman's hovercraft as the madman growled. "Tails is here, so Sonic must be with him too!"

Mikoto and Dia followed the blue plane with their eyes and saw how Missile Wrist tried to hit the plane, but the fox, Tails, maneuvered the plane and missed the attacks. Then Tails shot bullets at Missile Wrist, but it didn't worked just like with the police. Missile Wrist shot its missile wrist and hit the propeller of the plane. The plane was about to crash when it suddenly transformed into a jet plane.

Mikoto was impressed by the transformation until Missile Wrist tried to hit the plane again and again, but Tails avoided the attacks. The lilac hedgecat had enough of watching.

"I must go and help them", she said. When she was about to jump over to the roof of the skyscraper, she saw a door open behind Missile Wrist and a red echidna ran out at the same time as an elevator opened next to the door and a pink hedgehog in a red dress came out with a big red/yellow hammer. The pink hedgehog ran towards the robot and hit it with her hammer, but it didn't do any damage. Missile Wrist turned its attention on the hedgehog and grabbed her.

The red echidna was about to attack Missile Wrist, but Eggman blocked his way. "Hold it, Knucklehead. One more step and the girl's a goner…", Eggman snapped his fingers and the robot squeezed the poor hedgehog as she screamed in pain. The red echidna, Knuckles, cold sweated and glared angrily at Eggman.

"You coward! Let Amy go!" Knuckles shouted.

"Coward? I'm only holding the girl to protect E-23!" Eggman told him before looking around. "There's still that hedgehog-"

"Spin Attack!"

A purple ball hit Missile Wrist from behind and the move surprised the robot that it threw Amy up in the air. The ball bounced up and unfolded to reveal Mikoto. She quickly grabbed Amy bridal style and landed gently on her feet on the roof. Eggman and Knuckles looked surprised to see the hedgecat.

Mikoto glanced down at Amy, "Are you okay?"

Amy looked shocked for a second before she nodded, "Y-Yeah…"

Mikoto put her down and turned her attention on Missile Wrist. Dia flew over to her and glared angrily at Eggman.

"And who are you? I've never seen a hedgehog with a cat's tail before", the madman asked.

"What?!" Eggman exclaimed and turned towards the streets to see a blue light coming towards the skyscraper.

"My Sonic is coming to rescue us!" Amy exclaimed happily.

Eggman and Missile Wrist went to the edge of the roof and bent down to see a blue ball coming up. "Fire!" Eggman commanded.

Missile Wrist shot several missiles towards Sonic and one of them seemed to have hit the blue hedgehog when he suddenly shot up at the sky above Eggman and Missile Wrist.

"Above!" Eggman shouted. Missile Wrist shot out its missile wrists again to hit Sonic, but Sonic rolled on top of one and jumped off to stand on the other. He didn't take the battle seriously and kept fooling around with the robot.

"You bastard! You're making fun of me!" Eggman growled.

"Is he always like that in battles?" Mikoto asked the other two anthropomorphic animals.

"Yeah. Most of the time", Knuckles answered and turned his attention on Sonic. "Sonic! It's about time you started to attack!"

"Okay!" Sonic said and sat still on one hand as Missile Wrist brought its arm back into place. The robot looked at him while Sonic stuck his tongue out at him and pulled his eyelid down. Missile Wrist was not happy with that and raised his other arm and slammed it on its right arm and broke it in procession. Sonic had jumped up in time and rose higher into the sky.

"Fire!" Eggman ordered once again.

Missile Wrist shot up missiles into the sky and exploded when they hit Sonic. Mikoto heard Amy gasp worriedly while Dia looked worried. Eggman cheered to himself when Sonic suddenly came out from the smoke, rolled up into a ball, and attacked Missile Wrist. He went through the robot's head and straight down its body. It caused an explosion from the robot and the group covered their eyes from the smoke.

When the smoke had cleared up, everyone saw Eggman covered in dust and bruises. Sonic stepped up and smirked at the madman. "You lose."

Eggman shook in anger, "This isn't over, blue boy…" He flew away from the skyscraper with his hovercraft. "You haven't heard the last of Eggman! Soon I will rule this world, this universe, and the Chaos Emeralds will be mine!"

"Sonic, oh Sonic!" Amy shouted and ran over to the blue hedgehog with tears in her eyelids and hugged him. "You're okay!"

"T-Take it easy!" Sonic groaned

"For a while, I really thought that I wouldn't see you again!" Amy cried and hugged her blue hero even tighter.

"Amy… Please let me go!" Sonic persisted.

Mikoto smiled lightly at the scene with Dia, who sighed happily that the battle was finally over. Sonic noticed the purple hedgecat and her Chao partner and was about to ask her something when they heard a couple of footsteps from behind. They turned around and saw humans dressed in black uniforms and held weapons aiming towards the anthropomorphic animals. Dia shivered in fear while Mikoto held her protectively.

Tails steered his plane towards the group with a string ladder attached to the side of the plane. Sonic held onto Amy and grabbed a hold of the ladder. Mikoto put Dia on her left shoulder, jumped up and grabbed the ladder as well.

"Hey, Knuckles! Come on!" Sonic called out to the red echidna, who was still standing there at the roof.

"Please, Knuckles! Let's go!" Amy called him when he didn't budge at all. He finally snapped out of it, smirked at the soldiers and ran towards the plane.

"Fire!" the captain ordered and shot along with the other soldiers. Dia closed her eyes and shook in fear when she heard the gun shots.

Knuckles ran away from the bullets and leapt towards the ladder. He managed to grab it when the plane was about to fly away from the building. Tails went up higher into the sky to avoid the obstacles.

"We'll go back to my house, guys!" the human boy said with a smile.

"Cream and Cheese are already there waiting for you!" Tails added.

"Wow, them too? So we're all here together!" Amy exclaimed happily.

*These guys must be friends or something…*, Mikoto thought.

"Sorry, but I have my own things to do!" Knuckles informed them. Mikoto turned her head at Knuckles with a confused look. The red echidna let go of the ladder and fell backwards.

"Knuckles!" Amy called out to him.

"See you around!" Knuckles glided away safely somewhere down below.

"Knuckles…why…", Amy wondered.

"Because he's got his own mission to fulfill", Sonic explained.

That caught Mikoto's attention, *So this echidna have his own mission? Just like me!* The purple hedgecat looked at the sky and saw it was slowly turning into orange by the sundown.

Tails arrived to the boy's home, which was a mansion, and Mikoto noticed there was a little rabbit girl and another Chao there waiting for their friends. An old man in a white lab coat stood there as well.

Sonic let go of the ladder before Tails landed the plane outside of a garage and landed on his feet with Amy in his arms. Mikoto did the same thing and walked over to the group that was busy with reunion. She kept a small distance from them and smiled lightly to see everyone happy.

The other Chao noticed Dia and flew over to her. The two Chao exchanged some words before they started to play tag. The little rabbit heard her Chao friend laugh and turned around to see Mikoto, who followed the two Chao with her eyes and chuckled lightly while they played. The rabbit walked over to Mikoto with a smile and gained her attention.

"Hi, I'm Cream and I see your friend have already met Cheese", the rabbit introduced herself and bowed lightly. "Pleases to meet you!"

"Nice to meet you too, Cream", Mikoto nodded her head.

The rest of the gang walked over to Mikoto and Dia flew back to the purple hedgecat and sat down on her head. Cheese flew back to Cream and floated beside her.

"I'm NOT Amy's boyfriend!" Sonic exclaimed. Everyone laughed at Sonic while Mikoto thought, *I feel like I will enjoy being with them, but I still need to find out who I am and collect the Chaos Emeralds…*
